Answer 1

You may want to overrive the onRestart() method - it will be invoked if your Activity has been stopped previously; while it won't if it's the first time it runs (or if it has effectively been killed in the meantime).

Be sure to read the Activity life cycle there: http://developer.android.com/guide/topics/fundamentals.html#lcycles to understand what happens when.

Answer 2

Check out the order in which the life cycle states appear. You could override onStart, onPause, onResume, onStop, onCreate, onDestroy etc functions by adding Toasts to see the sequence. Then you can override them as per your programming requirements.
